For real?

Your e-mail provider has tons of style rules in its stylesheet that set 
font sizes in pt.

The google.com front page has font sizes in pt.

It's pretty common.

How is it the right thing to do to purposefully break lot of existing 
pages?  Why would UAs ever do that?  Why would it be good for users or 
authors?

Why is it good if people using a web browser in 5 years can't view 
pages, whether archived or just still extant, that were authored any 
time in the last 16 years?

It's not clear that this is a "problem".  I suggest you read some of the 
things David Baron has written about versioning proposals in the past 
(e.g. in the context of versioning HTML, which is likewise unversioned).
